CRUSHlNG-ROLL.

Specification of Letters Patent] Patented Oct. 2, 1906.

Application filed February 23, 1906. Serial No. 302,533-

' GUEZ, a citizen of the Republic of Cuba and a resident of Caibarien,in the Province of Santa Clara, Republic of Cuba, have invented a newand Improved Crushing-Roll, of which the following is a full, clear, andexact description.

This invention relates to crushing-rolls, and especially to the class ofrolls used in the treatment of sugar-cane preparatory to extracting thejuice.

The invention consists in the construction of a roll to be describedmore fully hereinafter, and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical cross-section taken through a crushing-roll of myinvention. This view is taken in the plane of the line 1 1 of. Fig. 2.Fig. 2 is substantially a front elevation of the crushing-roll, aportion of the same being shown in cross-section; and Fig. 3 is across-section taken substantially in the same plane as the line 1 1 andshowing, upon an enlarged scale, a portion of the rolls at the pointwhere their faces come together.

Referring more particularly to the parts, 1 represents the roll of myinvention. In using the roll I prefer to mount it upon a horizontal axleor shaft 2, supported in suitable pedestals or frame members 3, andadjacent to the said roll 1 I provide a roll 4, which may have a plainface, as shown. Gear-wheels 5, attached to the axles or shafts of therolls, enable them to be turned in unison in opposite directions, andone of the shafts, as the shaft 2, is adapted to be driven continuouslyby means of a suitable belt 6. face of the roll 1 as indicated in thefigures.

The roll being of substantially cylindrical form I provide its outerface with teeth 7, disposed in longitudinal rows. These teeth areobtusely V-pointed, as indicated most clearly in Fig. 2, so that theypresent apexes 8, presenting edges 9, disposed transversely with respectto the axis of the roll. Between these apexes recesses 10 are formed,

I form the surwhich terminate below in transversely-disposed edges 11.In this way the entire outer surface of the roll is covered with aplurality of rows 12 of the said teeth, and these teeth are formed instaggered relation with respect to each otherthat is, the teeth ofadjacent rows lie intermediately with respect to each other, the teethof one row lying opposite the recess of the next, as will be readilyunderstood. Between the rows of teeth the material of the roll is formedinto longitudinally-disposed ribs or webs 13. These webs are extendedupwardly, so as to be substantially in alinement with the apexes of theteeth, and they extend downwardly to the bottoms of the recesses 10.While the teeth 7 are of massive form and the width ofthe teethrelatively great, I prefer that the ribs or webs 13 should be relativelysmall, as indicated, so that these ribs or webs operate as cutters tolacerate the cane transversely as it passes between the roll 1 and theroll 4.

' At the ends of the body of the roll Iprefer to provide the same withenlargements or collars 14, which project laterally and slightlyoverhang the extremities of the cooperating roll 4, as indicated in Fig.2. The manner of attaching the roll 1 to the shaft 2 is immaterial, andany suitable means may be adopted.

It should be understood that the cane will be passed between the rolls 1and 4 in the usual manner. As the cane passes between the rolls theteeth 7 operate to split the woody fiber or covering and squeeze thesame, while the webs 13 operate to cut the material of the canetransversely, as stated above. In this way a very efficient lacerationof the body of the cane is effected, which is highly conducive to aneflicient extraction of the juice thereafter.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A crushing-roll having teeth formed in straightrows extending longitudinally of said roll, and having straight webslying between said rows and extending longitudinally thereof.

2. A crushing-roll having a plurality of rows of teeth extendinglongitudinally thereof, the teeth in said rows being disposed in name tothis specification in the presence of staggered relation With respect toeach other, two subscribing Witnesses. whereby a tooth in one IOW liesopposite del pressions in the adjacent rows, said roll JOSE PELAEZRODRIGUEZ 5 further having Webs extending longitudi- Witnesses:

nally thereof and separating said rows. w H. C. NEWooMB,

In testimony whereof I have signed my JOAQUIN VARGOS.
